a) pole arc = ratio of armature axial length to armature diameter * pole pitch
b) pole arc = ratio of armature axial length to armature diameter + pole pitch
c) pole arc = ratio of armature axial length to armature diameter – pole pitch
d) pole arc = ratio of armature axial length to armature diameter / pole pitch
b) pole arc = ratio of armature axial length to armature diameter + pole pitch
c) pole arc = ratio of armature axial length to armature diameter – pole pitch
d) pole arc = ratio of armature axial length to armature diameter / pole pitch
